Web Hosting - Domain Name Changes and How They Affect You New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it. When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties. One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another. Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here. DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low. In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was. A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed. The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world. Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching. In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data. A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed. Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random. But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies. That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely. In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address. So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.

The History of Writing Tools (history of writing tools) Writing tools are essential to written communication. A person is not able to write without the proper writing tools. However, many people don’t realize that writing tools did not just pop into existence; writing tools have a long history. Writing tools have helped societies write their history and bring civilizations to life. The history of writing tools begins with the cave man that invented the sharpened-stone, which was later developed into the first writing tool. Cave men used these instruments to scratch pictures onto the walls of cave dwellings. The drawings were said to represent events in the daily life of the cave men, such as the planting of crops and hunting victories. Clay was later discovered, which made portable records possible, and many merchants of the time used clay token with pictographs to record the quantities of materials being traded and shipped. The Greeks developed the earliest form of pen and paper. They used the writing stylus, which could be made of metal, bone, or ivory, to make marks on wax-coated tablets. The tablets used by the Greeks were made in hinged pairs that were closed to protect the scribe’s notes. Cadmus was a Greek scholar who seemingly invented the written letter, which is a text message on paper sent from one individual to another. The written letter proved to be a major event in the history of writing tools, and was the starting point for the development of ink. “Indian Ink” was developed by the ancient Chinese society, and perfected for writing. The ink was originally designed for blacking the surfaces of raised stone-carved hieroglyphics, but was later used for writing. This early ink was made of a mixture of soot from pine smoke and lamp oil mixed with the gelatin of donkey skin and musk. By the year 1200 B.C. the ink had become common as a writing tool. Inks were also developed by other cultures, who used natural dyes and colors derived from berries, plants, and minerals to create them. The different colors of inks had ritual meanings attached to each color in early writings. In the history of writing tools the development of ink paralleled the introduction of paper. Early cultures such as the Egyptians, Romans, Greeks, and Hebrews used papyrus and parchment paper to write on. Romans invented a reed-pen for parchment and ink, from the hollow tubular-stems of marsh grass and the jointed bamboo plant. The bamboo stems were converted into writing tools that resemble the fountain pen. The plant was cut at one end into the form of a pen point, and ink filled the stem, by squeezing the reed, writers could force the ink from the point and write on parchment paper. The early forms of ink and paper were great developments in the history writing tools, but were often unstable. A stable form of ink was developed in 400 A.D., which was a composite of iron-salts, nutgalls, and gum. The ink was seen as having a bluish-black hue when applied to paper, but quickly becoming a darker black color, and fading after years and appearing as a dull brown color. The Chinese created a wood-fiber paper in 105 A.D., but it was not known to other cultures until 700 A.D. when the Japanese learned the secret. Eventually, the wood-fiber paper was brought to Spain in 711 A.D., but was not widely used in Europe, as most European societies did not use paper until the 14th century. The quill pen is also a major invention in the history of writing tools. The quill pen was introduced to the world in 700 A.D. The pen was made of bird feathers, and the strongest quills were typically taken from live birds from the outer left wing feathers. After the development of the quill pen, plant fiber paper became the popular medium for writing. Then another invention changed the history of writing tools; Johannes Gutenberg invented the printing press. This invention has led to various other developments in printing and writing tools. Writing tools are essential to writing, and without the development we would not be able to show others our ideas and thoughts.

Definition of copyright infringement Protect Yourself: Know the Definition of Copyright Infringement As you’re creating something, you may wonder what copyright infringement actually is. It’s necessary, if you’re creating a work – albeit written, musical, videos, software or some other form – that you know the definition of copyright infringement. This issue is very complicated, and not very easily spelled out in plain English, so please make sure that if you’re ever unsure to contact a copyright lawyer immediately to ensure you’re using copyrights in a legal method appropriate to the medium. As I mentioned earlier, a definition of copyright infringement is difficult, at best. Copyright infringement is defined by the jurisdiction – the United States of America has different copyright laws than the United Kingdom, or Australia, or Russia, or even China. Because of this fact, you should first, before anything else, check the laws in your jurisdiction (country, city & province) before using something that isn’t in the public domain. For our definition of copyright infringement, the public domain is a place where works are that aren’t copyright-able. Works that aren’t copyright-able include ideas, works that aren’t eligible (150 years-old documents, or older – think Beethoven and Frankenstein), data that isn’t categorized in a creative way (this could be a database, such as a phone book or other publicly-accessible data), or items that the owners have specified creative commons copyrights. As you can see, copyright law is rather complicated. Wikipedia.org gives us the definition of copyright infringement as: “Copyright infringement (or copyright violation) is the unauthorized use of material that is protected by intellectual property rights law particularly the copyright in a manner that violates one of the original copyright owner's exclusive rights, such as the right to reproduce or perform the copyrighted work, or to make derivative works that build upon it. The slang term bootleg (derived from the use of the shank of a boot for the purposes of smuggling) is often used to describe illicitly copied material.” Our definition of copyright infringement includes the works of creative commons. Creative commons is an organization that allows for the copyright author to determine the uses available for people who want to use their works – for such items as for audio, images, video, text, educational materials, and software. It allows for the copyright owner to allow people to use their works for non-commercial, commercial, no derivatives, share alike, or just by giving attribution. Creative Commons is a license granted by the copyright holder, and can be used in both online (electronic internet) works and offline works. There are many places you can go to get a definition of copyright infringement. The most reliable definition of copyright infringement would be from your local copyright lawyer – they will know exactly what in your jurisdiction is legal or not, and how you can use other peoples’ works or protect your own. The real definition of copyright infringement comes from your jurisdictions statutes. In the United States of America, our jurisdiction’s copyright laws are contained in Title 17 of the United States Code, §501 - §513. You can also find a definition of copyright infringement through such organizations such as the European Union or World Trade Organizations. While s legal country or organizational definition of copyright infringement is hard for the layperson to understand, a copyright lawyer will help you to figure out what it is that your work needs to be protected against copyright infringement, or to protect yourself if you intend to use the work of another writer, director, or musician.
